Wilwood Dynapro Lug Mount Dual Rear Dynamic Kit SA Drilled M-W/Lamb Ends 1/2in Studs

This is the Wilwood Dynapro Lug Mount Dual Rear Dynamic Brake Kit, part number 140-12555-D. It's designed for drag racing applications where the rear brakes are crucial for stopping power and often endure high heat. The kit features a unique lug-drive rotor mounting system that uses a single internal snap-ring to hold the rotor in the hat, eliminating traditional rotor bolts. This design allows the rotors to expand and contract freely with heat cycles, preventing thermal stress from distorting the rotor attachment points and helping them stay flatter and run truer.

The stainless steel rotor inserts within each lug-drive slot are spring-loaded and replaceable. They protect the aluminum hat from wear caused by the stainless steel rotor pressing against it during braking. This attention to detail helps maintain the integrity and performance of the braking system over time. The kit includes rotors with a drilled pattern for improved heat dissipation and a 1/2 inch stud size for the Lamb or M-W ends.

This kit is a solid option for high-performance drag cars that demand consistent and reliable rear braking under extreme conditions. Because it's a rear brake kit, you'll want to ensure it's compatible with your specific vehicle's rear axle and suspension setup. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
